The cell theory consists of:
1. all living organisms are made up of cells
2. cells are the basic structural/organizational unit of all organisms
3. all cells come from pre-existing cells
A balance chemical equation is an equation describing a chemical reaction with the right number of molecules to cancel out each side of the equation.
For example:
H2 + O2 —> H2O
Make sure the number of molecules in your reactants equal the number of molecules in your product
2H2 + O2 —> 2H2O
(4 hydrogens and 2 oxygens = 4 hydrogens and 2 oxygens)
Not quite sure but would say Archaebacteria with the most confidence... hope this helps good luck
The answer is all of the above
